Args:

other: Another Dimension, or a value accepted by as_dimension.

Returns:

A Dimension whose value is the sum of self and other.

__div__

__div__(other)

DEPRECATED: Use __floordiv__ via x // y instead.

This function exists only for backwards compatibility purposes; new code
should use __floordiv__ via the syntax x // y. Using x // y
communicates clearly that the result rounds down, and is forward compatible
to Python 3.
